Hyalomma lusitanicum 88 64 94 72
Hyalomma marginatum 95 99 96 98

Rhipicephalus bursa 95 98 95 99
  1. Values indicate the number of null models (n = 99) whose median AUC scores were significantly exceeded by those of observed models (1000 random 60:40 training:testing data splits per model). Significant differences identified using post hoc multiple comparison tests with Bonferroni corrected critical values from the t distribution. Attainment by an observed model of a median AUC score significantly higher than those of 95 null models was deemed to indicate a significant relationship between the climate predictor variables and the distribution of the tick species. Underlined values indicate that no significant relationship was identified for that species’ observed model(s)
